TL;DR: In this paper, the water absorption of polymeric coatings was measured by coating capacitance method in 3.5% NaCl aqueous solution, and the results indicated that water uptake of epoxy coatings modified with 1.0% γ-APS decreases compared with pure epoxy coating, whereas larger amounts of sliane result in the deterioration in performance against water permeation, due to the excessive consumption of epoxide group in epoxy resin by amino-group in silane agent, thus reduce the cross-linking of epxoy coating as a result of

TL;DR: In this paper, a mathematical drying model is presented, the simulations of which can match and explain experimental drying rate data of two previous investigations with latex films, but in agreement with observations, simulations suggest that during the falling rate period of the drying process of a latex film, a porous skin of partly coalesced latex particles is indeed formed, which limits transport of water vapour from the receding air liquid interphase to the surface of the film.
